Like Disney, Cunard will ban cigarette smoking on balconies due to feedback from past passengers and customer research. "This change has been made for the safety and comfort of our passengers and means that all passengers will be able to enjoy full use of their private balconies, without the effect of drifting smoke," a spokeswoman told Cruise Critic.

Starting February 2 onboard Seabourn Pride, the cruise line will no longer permit smoking in passenger cabins. The line was one of the last to allow passengers to smoke in their cabins.

Additionally, Seabourn will ban smoking on some balconies. In particular, passengers in category B suites on Seabourn Pride, Spirit and Legend will no longer be allowed to light up on their balconies, while those in category CS and OW suites will continue to be allowed to smoke. The difference, a spokesman said, is that category B balconies are not actually step-out balconies, but are instead sliding doors that open within the cabin, "ineffective in isolating smoke from the suite."
